Fiber-Elastomer Adhesion Variables

A summary of factors important to adhesion research is presented as a starting point for a philosophy of adhesion. Adhesion of fabrics from nylon and polyester yarns to rubber with three adhesive systems (dips) is examined from the standpoints of: adhesion development with increased dip-curing time, location of specimen failure sites, effects on adhesion of polar and nonpolar liquids, and relationship of adhesion performance to wetting. Results are interpreted to demonstrate the types of adhesive bonds involved, the preferred type of adhesive for polyester fibers, and the importance of relating relative adhesive strength values to the sites of failure. An example of what appears to be mechanical adhesion to roughened polyester film is discussed.
